A species of deep-sea fish uses a genetically determined bioluminescent lure to attract prey. Fish with brighter lures are more successful at attracting food and have a higher chance of surviving to reproduce. The species produces hundreds of offspring, but only a few survive to adulthood. However, every individual in the current population has a lure of the exact same brightness. Based on these conditions, why is the average lure brightness in this population unlikely to increase over time?
